3D rendering performance depend upon hardware configuration and some software settings. Large 3D scenes require both processing power and adequate graphical capabilities of the computer.
1. Using the 64-bit versions of RapidAuthor tools will improve large projects’ performance by using more available system RAM. 32-bit browsers are limited to 2GB of RAM and may degrade your scene’s performance (please refer to this articlefor more details).
2. Check Cortona3D Viewer renderer options:
· In RapidManual (or RapidCatalog, or RapidLearning) go to Tools > Options > 3D View > Renderer and make sure that DirectX is selected. To improve your 3D viewing experience, enable Real-Time Anti-aliasing (requires powerful graphics card).
· In RapidManual (or RapidCatalog, or RapidLearning) go to Tools > Options > 3D View > Renderer > Advanced and enable Phong lighting model by ticking the box. This option transfers part of rendering to the graphical processing unit improving both speed and quality (requires powerful GPU).
3. Check your 3D data size (File > Project Information). Cortona3D tools operate in meters. Visible 3D geometry size represents the current size of the assembly's bounding box. It may also impact 3D scene performance. Your 3D size should reflect actual size of the model. Measurement units in your Import Plugin Settings should be changed to get correct scaling of the model (select Import Plugin and click Settings, e.g. “Convert millimeters to meters” = 0,001 multiplier).
